Android 标题 居中 .

1在onCreate()方法中加上这三句话：

requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
 setContentView(R.layout.main);
 getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,R.layout.title);

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_gravity="center">
        <TextView android:id="@+id/textTile"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="title" />
</LinearLayout>

注：另外设置字体大小、颜色等在title文件的textTitle中设置
